Yeah it does definitely depend on the rates you get charged for gas and electric and if you have solar. It was a few years ago when I did the math and gas was cheaper but not by enough for me to go to the expense of having a gas line extended into the house and buy the heater and so on.
The price of gas (and electricity) is skyrocketing.
If you have solar, a properly installed Reverse cycle is much more efficient and much more cost effective.
Make sure you get the biggest capacity Reverse Cycle A/C you can afford and make sure the Heat Exchanger is installed on the south side of the house.
A 30W reverse cycle would need to run constantly, compared to a 70W which would only need to run 1/3-1/2 the time.
The heat exchanger won’t work efficiently if it is out in the sun.
